Description

Technical Field

[0001] This utility model relates to the field of rapeseed oil processing technology, and in particular to a rapeseed oil refining tank. Background Technology

[0002] As an important source of oil in the human diet, rapeseed oil is derived from the seeds of Brassica napus and Brassica oleracea var. nana. These seeds are rich in components, with an oil content ranging from 22% to 49%, a protein content of 21% to 27%, and a phospholipid content of about 1%. Nutritionally, rapeseed oil contains an average of 61% oleic acid among its unsaturated fatty acids, with beneficial oleic and linoleic acids ranking among the highest in content among various vegetable oils.

[0003] However, unprocessed crude rapeseed oil has obvious defects: it is yellowish-green in color, has a high erucic acid content, and has a unique strong odor. It must undergo a refining process to become a qualified edible oil.

[0004] To refine rapeseed oil, various impurities must be removed from the crude oil, including solid impurities, free fatty acids, phospholipids, waxes, pigments, and off-odors. However, current refining technology and equipment have many problems that seriously affect the refining effect: First, the refining process often relies on alkali refining with substances such as edible alkali, which leads to a deterioration in the color and taste of the rapeseed oil, an aftertaste during storage, and difficulty in meeting high-quality and environmentally friendly standards. It also increases costs and reduces efficiency. Second, the filtration process has prominent problems. The filter screen easily accumulates impurities and is difficult to clean. Frequent manual cleaning not only increases costs but also interrupts the continuity of processing. Third, the cleaning structure of some equipment is poorly designed. For example, when the cleaning plate rotates with the stirring rod, it agitates the crude oil and hot water, causing phospholipids, proteins, and impurities to re-mix into the crude oil, requiring it to be allowed to settle again, which seriously affects efficiency. In addition, solid impurities such as oil cake mixture remain on the filter screen after filtration, making it difficult to discharge through the slag outlet. This can easily enter subsequent processes and contaminate the oil quality, requiring frequent disassembly and cleaning of the filter screen. Fourth, the stirring rod of the stirring device is prone to adhering to a large amount of rapeseed crude oil, which is not only inconvenient to clean but also wasteful when discharging oil.

[0005] These problems collectively restrict the quality, efficiency, and economy of rapeseed oil refining. Therefore, developing a rapeseed oil processing and refining tank that can solve the above problems has become an urgent need for the industry.

[0006] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art.

Detailed Implementation

[0022] The following is a detailed explanation with reference to the accompanying drawings.

[0023] Example 1

[0024] This utility model provides a rapeseed oil refining tank, such as... Figure 1 and Figure 2 As shown, the system includes a main body 100. The main body 100 is internally divided into an oil inlet assembly 200 and a refining assembly 300. The oil inlet assembly 200 includes an oil inlet chamber 201, a guide plate 202 disposed within the oil inlet chamber 201, and a filter screen 203 located vertically below the guide plate 202. The guide plate 202 is inclined towards the filter screen 203. A 204 is disposed vertically below the guide plate 202. The filter screen 203 is inclined towards the waste bin 204. A buffer bin 205 is disposed vertically below the filter screen 203. An oil outlet 206, connected to the refining assembly 300, is provided at the vertical upper end of the buffer bin 205. The main body 100 is internally divided into an oil inlet assembly 200 and a refining assembly 300. The rapeseed oil is guided to the filter screen 203 by the guide plate 202 in the oil inlet assembly 200. The inclined guide plate 202 and the filter screen 203 achieve preliminary separation by gravity. Impurities enter the impurity chamber 204 under the action of gravity and fluid flow. The filtered rapeseed oil enters the buffer tank 205 and then enters the refining assembly 300 through the oil outlet 206. This realizes the orderly connection between filtration and refining in rapeseed oil processing, improves the continuity and efficiency of the overall processing flow, and reduces the interference of impurities on the subsequent refining process.

[0025] According to a preferred embodiment, such as Figure 3 As shown, the guide plate 202 covers the inner wall of the oil inlet chamber 201 to guide the fluid to the filter screen 203. The inclined surface of the guide plate 202 is streamlined. The filter screen 203 is positioned to receive the fluid flowing down from the guide plate 202. An oil inlet for inputting rapeseed oil to be processed is also provided vertically above the oil inlet chamber 201. This oil inlet is aligned with the guide plate 202. The guide plate 202, covering the inner wall of the oil inlet chamber 201 and employing a streamlined inclined surface, minimizes resistance during the rapeseed oil flow process. In particular, it disperses the input fluid through inclined collisions, reducing the generation of bubbles and eddies on the fluid surface in a stepped flow manner, preventing oil stagnation. Simultaneously, it concentrates all the rapeseed oil flowing into the oil inlet chamber 201 and guides it to the filter screen 203, ensuring that all the oil passes through the filtration stage, thus improving the thoroughness of filtration. The filter screen 203 precisely receives the fluid flowing down from the guide plate 202, preventing oil overflow and ensuring the stability of the filtration process.

[0026] According to a preferred embodiment, a slide rod 101 is fixedly connected to the inner wall of the oil inlet chamber 201 and is provided vertically above the filter screen 203. The slide rod 101 extends at the same angle along the inclined direction of the filter screen 203. A cleaning brush 102 is sleeved on the slide rod 101, covering the side of the filter screen 203 perpendicular to the slide rod 101. The slide rod 101 extends along the inclined direction of the filter screen 203 and at the same inclined angle as the filter screen 203. The cleaning brush 102 is sleeved on the slide rod 101 and covers the side of the filter screen 203 perpendicular to the slide rod 101, so that the cleaning brush 102 can move stably along the surface of the filter screen 203, which can thoroughly clean the filter screen 203, prevent impurities from clogging the filter screen pores, maintain the filtration efficiency of the filter screen 203, and extend its service life.

[0027] According to a preferred embodiment, a push rod 103 and a drive motor 104 connected to the push rod 103 are connected to the cleaning brush 102. The drive motor 104 is positioned vertically above the filter screen 203 and embedded in the inner wall of the oil inlet chamber 201. The drive motor 104 moves parallel to the slide rod 101. The drive motor 104 drives the cleaning brush 102 to move along the slide rod 101 via the push rod 103, realizing automated cleaning operation of the cleaning brush 102 without manual intervention, thus reducing labor costs. The drive motor 104 is embedded in the inner wall of the oil inlet chamber 201 and its driving direction is parallel to the slide rod 101, avoiding obstruction of oil flow by the motor and ensuring the stability and effectiveness of the cleaning process.

[0028] According to a preferred embodiment, the waste bin 204 has a waste outlet at its vertical lower end. The waste bin 204 and the buffer bin 205 are arranged adjacent to each other at a distance. The waste outlet at the lower end of the waste bin 204 facilitates the periodic cleaning of collected impurities, preventing the accumulation of impurities from affecting the normal operation of the oil inlet assembly 200; the adjacent and spaced arrangement of the waste bin 204 and the buffer bin 205 effectively prevents impurities in the waste bin 204 from mixing into the buffer bin 205, ensuring the purity of the rapeseed oil in the buffer bin.

[0029] According to a preferred embodiment, a float 207 is provided inside the buffer tank 205. A conduit 208 is provided on the float 207. The conduit 208 is made of a flexible material to move vertically with the float 207, and the conduit 208 is connected to an oil outlet 206. The oil outlet 206 is located at the upper end of the buffer tank 205, and the conduit 208 moves with the float 207, so that the oil drawn from the conduit 208 is the settled rapeseed oil, avoiding the suction of sediment from the bottom of the buffer tank 205. The float 207 moves vertically with the change in oil level in the buffer tank 205, and the flexible conduit 208 moves accordingly, so that the conduit 208 always draws the settled rapeseed oil from the upper layer of the buffer tank 205, avoiding the suction of sediment from the bottom to the refining component 300, improving the quality of rapeseed oil entering the refining stage, and reducing the processing burden of the refining component.

[0030] According to a preferred embodiment, a plurality of through holes 209 are provided through the float 207. The through holes 209 facilitate the vertical movement of the float 207, and at the same time prevent disturbance to the rapeseed oil in the buffer tank 205 during the pumping process through the conduit 208, thus preventing unfiltered substances that may have settled at the bottom from being drawn into the refining component 300. The through holes 209 on the float 207 provide flow space for the vertical movement of the float 207, ensuring its smooth rise and fall with the oil level; on the other hand, they reduce disturbance to the rapeseed oil during pumping, preventing unfiltered sediment at the bottom from being stirred up and entering the conduit 208, further ensuring the purity of the rapeseed oil entering the refining component 300.

[0031] According to a preferred embodiment, a pump is installed at the connection point of the oil outlet 206 between the buffer tank 205 and the refining component 300. The pump installed at the oil outlet 206 provides power for transporting rapeseed oil from the buffer tank 205 to the refining component 300, effectively controlling the oil transport speed, enabling the refining component 300 to stably receive the oil to be refined, and ensuring the continuity and stability of the refining process.

[0032] According to a preferred embodiment, the refining assembly 300 includes a refining tank 301, a stirring element 302 located within the refining tank 301, and a drive motor 303 connected to the stirring element 302. The stirring element 302 penetrates the inner wall of the refining tank 301 and is connected to the output shaft of the drive motor 303. Driven by the drive motor 303, the stirring element 302 within the refining tank 301 stirs the rapeseed oil, ensuring thorough mixing of the rapeseed oil and refining agent, while simultaneously guaranteeing uniform heating of the oil, improving refining reaction efficiency, shortening refining time, and enhancing refining effect. The refining tank 301 has an opening on its side connecting to the outside, facilitating the discharge of the refined rapeseed oil from the refining tank 301.

[0033] According to a preferred embodiment, a heating element is provided circumferentially in the refining chamber 301. The circumferentially arranged heating element in the refining chamber 301 can uniformly heat the rapeseed oil inside the chamber, avoiding localized overheating that could damage the quality of the rapeseed oil, ensuring that the refining process is carried out at a suitable temperature, and thus improving the final refining quality of the rapeseed oil.
